A bill of attainder (also known as an act or writ of attainder) is an act of legislature declaring a person or group of persons guilty of some crime and punishing them without benefit of a trial. Bills of attainder are forbidden by Article I, section 9, clause 3 of the United States Constitution.

Private bill is a general term referring to a proposal for legislation applying to a specific person; it is only a bill of attainder if it punishes. Previously, private bills were used in some Commonwealth countries to effect divorce
. Other traditional uses of private bills include chartering corporations, changing the charters of existing corporations, granting monopolies, approving of public infrastructure and seizure of property for those, as well as enclosure of commons and similar redistributions of property. Those types of private bills operate to take away private property and rights from certain individuals, but are usually not called "bill of pains and penalties". The last United Kingdom bill called Bill of Pains and Penalties was passed by Lords in 1820, but not considered by Commons; it sought to divorce Queen Caroline from King George IV and adjust her titles and property accordingly, on grounds of her alleged adultery, as many private bills dealing with divorces of private persons did.
